Abstract

Des espèces solubles contenant de l'azote sont éliminées de l'eau contaminée par la mise en contact de celle-ci avec des particules d'oxyde d'aluminium dans un réacteur et l'ajout suffisant d'acide sulfamique au réacteur pour ajuster le pH de l'eau contaminée à 5 ou moins afin de produire de l'eau traitée. L'eau traitée, qui possède moins d'espèces contenant de l'azote soluble que l'eau contaminée, est retirée du réacteur.
